Ruma Carburetor Replacement for Generac GP3250/GP3300/GP3600 - Part 0K95520119, Kit with gaskets & spark plug

Ruma's replacement carburetor is a direct-fit OEM-style unit and maintenance kit designed to restore fuel delivery for Generac GP3250, GP3300 and GP3600 series generators.

If your Generac-powered portable generator is hard to start, stalls under load, or runs poorly after sitting unused, a worn or clogged carburetor is often the cause. This Ruma assembly replaces part 0K95520119 and other equivalent Generac numbers, and ships as a complete maintenance package with gaskets, fuel line, clips, an air filter, insulator, mounting hardware and a spark plug so you can return the unit to reliable operation in one visit.

Will this carburetor fit my specific Generac model?

Yes — the unit is made to match the original Huayi OEM 0K95520119 dimensions and mount points, so it fits a broad set of Generac portable generators powered by 196cc–212cc engines. Verify the part numbers and engine size on your model label to confirm compatibility.

• Compatible with GP3250, GP3300 and GP3600 series models and many model variations.
• Replaces Generac part numbers such as 0K95520119, 0J5343A and 0H33750178.
• Fits engines in the 196cc–212cc range and specific model codes listed on generator plates.

What comes in the Ruma carburetor kit and why it helps?

This kit includes the carburetor body plus consumables you typically need when servicing a small generator: air filter, gaskets, fuel hose, retaining clips, an insulator, mounting nuts and a replacement spark plug. Having all parts together avoids multiple orders and ensures correct sealing and fuel routing when you install the carburetor.

• Complete gasket set and mounting hardware for a watertight fit.
• OEM-style air filter matched to the carburetor’s inlet for better filtration.
• Fuel line and clips to replace brittle lines that can leak or collapse.
• Includes spark plug to complete routine tune-up during installation.

How does swapping this carburetor improve generator performance?

Replacing a degraded carburetor restores correct fuel metering and airflow, which improves starting, idle stability and load response. A fresh carburetor and new filter reduce fuel leaks, allow smoother rev control, and reduce the need for repeated pull-start attempts.

• Improved cold starts and fewer pull attempts after installation.
• Smoother idling and steadier RPM under light to moderate loads.
• Reduced risk of fuel seepage and vapor lock from cracked lines or seals.

Are there generators from other brands this will work with?

Because several portable generators share the same carburetor and air-filter housing design, this Ruma assembly also fits compatible models from other makers. Cross-compatibility helps when you have a similar-sized unit from a different brand that uses the same mounting and intake geometry.

• Common replacement for Blackmax BM903600 / BMGN3600 carburetors.
• Works with certain Wen models (3500–4750 series) and some Duromax XP5500 variants that share the same housing.
• Matches ETQ and other manufacturers’ 2-inch pump applications that use the same carb layout.

Who is this for: This Ruma carburetor and tune-up kit is intended for owners, mechanics and fleet managers who operate Generac GP3250/GP3300/GP3600 portable generators or other compatible units and need a reliable, OEM-compatible replacement. It’s especially useful for units that have been idle, show fuel delivery symptoms, or require routine maintenance to maintain dependable emergency or job-site power.
